Everyone wants to feel optimistic about the future. Because there are always problems and struggles in this life, we always hope that things will be better in the future. There is a market, therefore, for teachers and prophets who will tell you that things are going to get better. They assert that God’s blessing is coming even if his people are living in sin or worshipping idols.

In these verses of Scripture, God confronted Judah’s leaders. Although these leaders are not directly specified, they are called “watchmen” (v. 10a), “dogs” (v. 10c, 11a), and “shepherds.” These titles suggest spiritual leaders. They might mean false prophets, priests, Levites, or all of the above. What are these spiritual leaders like?

They are supposed to be watchmen but they are blind (v. 10a-b) so they are unable to see spiritual danger when it comes.

Similarly, they are called “dogs” in verse 10c. Dogs were despised in ancient Judaism, so they were not bred and kept as pets but as helpers to shepherds. Instead of being on alert for predators of the sheep, however, these dogs “cannot bark... lie around and dream” because “they love to sleep.” Like the blind watchmen of verse 10a, they were worthless for alerting God’s people to spiritual danger.

Finally, “they are shepherds who lack understanding,” meaning that they do not care for the sheep but for their “own gain” (v. 11e) and pleasure (v. 12a-b).

The greatest indictment of these bad spiritual leaders is what they teach which Isaiah gave us in verse 12c-d, “tomorrow will be like today, or even far better.” Instead of warning Judah that God’s judgment was coming like a good shepherd, a good watchdog, and a good watchman would, these false spiritual leaders prophesy better days to come. Their intention is not to get God’s people to repent but to reassure God’s people that the best is yet to come.

One sign of a false teacher in any age, then, is a relentlessly positive message. When someone speaks for God but prophesies prosperity and hope only, with no discussion of sin, no warning about God’s judgment, and never a word (in this age) about the blood of Christ, that person exhibits the signs of false spiritual leadership described here in Isaiah 56.

I know what kind of teaching you get in our church but I also know that my voice is not the only spiritual influence you hear. Whether you read stuff on the Internet, listen to radio preachers or watch them on TV, think carefully about what you are being taught. Turn off anyone who prophesies only better days ahead with no call for repentance, no warnings of God’s judgment, no offer of hope through the death and resurrection of Christ. The good news, the best news, is that Christ died for our sins not that Jesus wants you to be rich and free from pain. So get your good news from that kind of teacher.
